What is the process of division that results in the formation of cells with half the usual number of chromosomes?
The process of meiosis.
Could crossing over occur during second meiotic division?
No, tips of homologous chromosomes cross over in Meiosis I. There are no homologous chromosomes by Meiosis I.
What happens to the remaining chromosomes from the last division in meiosis?
In meiosis all the chromosomes are incorporated into sperm cells whereas production of an unfertilized egg results in the leftover chromosomes incorporated into polar bodies.
What are the main differences between meiosis and mitosis division?
Mitosis produces cells with 46 chromosomes while meiosis produces cells with only half the chromosomes, 23.
Why do gametes have n numbers of chromosomes but not 2n?
Gametes are produced by the type of cell division called meiosis. During meiosis the number of chromosomes are halved. So if a cell starts off with 2n chromosomes and divides by meiosis the new cells will end up with n chromosomes.
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
only in meosis
What will separate in the first division in meiosis one?
chromosomes
What is the process of division that results in the formation of cells with half the usual number of chromosomes?
The process of meiosis.
Could crossing over occur during second meiotic division?
No, tips of homologous chromosomes cross over in Meiosis I. There are no homologous chromosomes by Meiosis I.
How many chromosomes would a cell have during metaphase 1 of meiosis if it has 12 chromosomes during interphase?
Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.
What is the name of the type of cell division that halves the number of chromosomes?
Meiosis
Meiosis is necessary to produce?
Meiosis is a special type of cell division. It is important to reproduce due to the sets of chromosomes in the cell.
What happens to the remaining chromosomes from the last division in meiosis?
In meiosis all the chromosomes are incorporated into sperm cells whereas production of an unfertilized egg results in the leftover chromosomes incorporated into polar bodies.
Which event makes meiosis a reduction division and why?
Meiosis 1 is called a reduction division because it reduces the number of chromosomes from diploid to haploid. This division results in the production of gametes.
What are the main differences between meiosis and mitosis division?
Mitosis produces cells with 46 chromosomes while meiosis produces cells with only half the chromosomes, 23.
The main results of meiosis?
Meiosis is a process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
Which cell division mitosis or meiosis has genetic variation and are not just identical cells?
Meiosis. Genetic variation is achieved by the random division of the chromosomes between the two daughter cells, and further recombination of specific genes between paired chromosomes before the division.
